Abstract: 47,579 PNEUMATIC OPERATING MECHANISM     FOR A CIRCUIT-BREAKER     ABSTRACT OF THE DISCLOSURE         The present invention relates to the utilization of a surge tank in the pneumatic line interconnecting the high-pressure reservoir with the pneumatic control valve controlling the operation of a driving, or operating piston reciprocally operable within a surrounding operating cylinder to operate a cirucit-breaker.  Preferably, the volume of the surge tank is roughly of the order of the piston-displacement volume traveled by the driving piston in its opening tripping movement of the circuit-breaker, when the mechanism is used to open the circuit-breaker.  However, the mechanism may also be used, if desired, to effect closing of the circuit-breaker.  Also, preferably, the inlet connection to the surge tank is somewhat restricted in diameter, so as to limit the gas volume exited from the main high-pressure reservoir, yet, however, nevertheless supplying a desirable biasing air pressure to countereact bouncing back, or return movement of the movable circuit-breaker parts at the end of the opening tripping operation of the associated circuit-breaker when the breaker contacts are fully open.

Abstract: ABSTRACT OF THE DISCLOSURE         This disclosure depicts a novel electron gun having at least one cathode having an electron emissive coating, a forward element and a plurality of electrodes interspaced between the cathode and the forward element. The electrodes and forward element each have at least one aperture wherein the apertures in the electrodes and forward element are coaxial and define at least one beam passageway for passing through the gun a stream of electrons emitted by the cathode during operation.  The beam passageway unavoidably forms a conduit for high velocity gas when the gun is located in a narrow neck of a television picture tube and the tube is evacuated of gas through a tubulator located at the rear end of the neck.  The improvements in the electron gun comprise a gas influencing element for reducing and perturbing the high velocity gas flow in the conduit at least in the region of the cathode as the tube is evacuated to suppress erosion of the cathode coating by prevening a violent flow of gas over the cathode.

Abstract: F23294-Canada ABSTRACT OF THE DISCLOSURE            A radiation detector made of hyperpure germanium has generally the shape of a follow cylinder with an outer generally cylindrical surface and an inner generally cylin-drical surface and is formed with a p+ contact and n+ contact.          One of the contacts is on the outer cylindrical surface of the semiconductor and the other is on the inner cylindrical surface, and both contacts are themselves cylindrical.  Each cylinder formed by a contact is open at at least one end thereof, the open ends being adjacent rather than opposite ends of the respective cylinders.  One of the contacts is a thin contact, having a thickness of one micron or less.   The germanium crystal is formed with an annular groove coaxial with the contacts and extending to within one millimeter of the thin contact at a position inward of the open end of the thin contact.  Thus, when a reverse bias is applied across the germanium crystal between the contacts, the resulting equipotential lines are relatively crowded at the groove, the electric field is of reduced strength adjacent the open end of the thin contact, and reverse leakage current is inhibited.

Abstract: A SIGNAL CUBER CIRCUIT            Abstract of the Disclosure The problems associated with large bandwidth requirements and of precisely controlling the relative magnitudes of the distortion components generated in predistorters are resolved in a bridge-type cuber circuit.  The cuber comprises a resistive bridge which includes a pair of oppositely-poled diodes connected in parallel with the resistor in each branch of one pair of opposite branches of said bridge.  The parameters of the cuber, which is balanced with respect to fundamental frequency signals, are adjusted so that predominantly third order intermodulation components are generated, and an impedance match with the signal source is obtained. The cuber circuit is used in a predistorter for cancelling third order distortion components produced in nominally linear amplifiers.

Abstract: ABSTRACT A wooden structural member or joist having a continuous tension chord and a continuous compression chord which are spaced apart and parallel.  The tension chord and compression chord form the effective top and bottom of the joist, the actual orientation depending on the type of load imposed upon the joist.  Dentations or dentated panels connect the side edges of the tension chord to the side edges of the compression chord, thus forming the two sides of the joist which has a hollow rectangular cross sectional shape.  The dentations are planar with two parallel edges and two non-parallel edges tapering together forming a broad end and a narrow end.  The face of the broad end is glued to the side edge of the compression chord, and the face of the narrow end is glued to the side edge of the tension chord.  The sides of the joist are discontinuous because of the dentated shape.  The dentations are coordinately spaced to allow pipes, conduits, ducts and other equipment to pass transversely through the joist.  The hollow rectangular shape also allows such equipment to pass longitudinally along the joist between the ends.

Abstract: ABSTRACT OF THE DISCLOSURE:     The invention is concerned with a process of producing carbon monoxide and hydrogen, which are separately discharged.          The process of the invention is characterized in that methanol vapor is dissociated on an indirectly heated, zinc-containing catalyst at temperatures of 200 to 500°C and at a pressure in the range of 2 to 50 bars to form an effluent gas in which the components CO and H2 constitute at least 90 % by volume, at least part of the impurities are removed from the effluent gas and the latter is separated into the components CO and H2 adsorption.  The use of methanol as starting material simpli-fies the process and reduces its cost since methanol can be stored and evaporated without great difficulties.
